[Demonology] AOE help

Hello everyone,

I need a bit of advice on AoE management in demonology spec.
On single targets i top the meters but then i crash and burn during trash packs.

What i usually do is Corruption every target (unless there are like 10+ like shadow pan monastery beginning).
HoGx2 on the highest health target
If i have enough Fury i use Meta and Doom targets as well while Hellfire is active.
And blade storm my pt.

I have a hard time managing a lot of targets at once, the tabbing the re-applying watching fury and cooldowns.
Any tips and tricks for a beginner?

What I've been taught, is to use HoG once, then quickly go demon form and use Chaos Wave, this trick makes the HoG do extra damage since it doesn't land until your in demon form, I then proceed to use immo aura and void ray with my pet spinning,

If i have low fury, I will use corruption and hellfire to build up,
Casting doom on the targets is a bit unnecessary since they'll die before being hit by a few ticks of doom, which doesn't make it worthwhile to cast in that situation.

Demonology AoE is widely different depending on a) the duration the mobs will be alive for and b) the amount of mobs. If it is like 10+ then I'd open up with sending your felguard in and cast 1 hand of gul'dan, and in the first 4 seconds of Shadowflame, cast more corruptions. As soon as the Shadowflame timer reaches 2 seconds, you NEED to cast the second Hand of Gul'dan and go directly into Meta. As soon as you're in Meta, I'd follow up with Carrion Swarm and then void ray until a) you run out of fury or b) you've got 1 or 2 HoG at the ready. If you've got 1 left, and they will survive the whole Shadowflame, I'd quickly hop out of Meta, cast HoG, then hop back in and reactivate Immolation aura and proceed the abovementioned action. I'll summarize;

hey,
which spells are affected by mannoroth’s fury? What I mean is, does is also ‘buff’ carrion swarm and hand of gul’dan? And what about the felstorm? Was thinking about trying demo on AOE fights, thanks for your help
